Using the Tool ‘Image Conversion’

CoPrA is able to convert PSD, TIFF and JPEG files using created ICC device profiles or DeviceLink profiles. This function is very useful for checking profile quality on images directly in CoPrA, since typical application programs often do not support all types of DeviceLink (i.e. RGB to CMYK) or multicolor profiles.

When running a demo version of CoPrA the tool Image Conversion will allow the conversion of images with CoPrA demo profiles for further evaluation in other programs (i.e. Photoshop).

After opening the image to be color converted (TIFF, JPEG or PSD), both a preview of the image as well as a possibly embedded profile is displayed.

You may choose to apply either a normal ICC conversion with source and target profile or a DeviceLink conversion. Based on the information of the embedded profile select the appropriate Source Profile from the drop-down menu. In a normal ICC conversion from Source to Target Profile you may specify the rendering intent. Besides the typical four ICC rendering intents Blackpoint Compensation is available as fifth option.

Note: Blackpoint Compensation is the relative colorimetric intent with additional black compensation, as in Adobe Photoshop.

A Video demonstrating the Image Conversion tool can be found here.

For a DeviceLink conversion select the desired DeviceLink profile from the drop-down menu Source Profile. In this case it is not necessary to select other options, such as the target profile or a rendering intent, therefore, these options are grayed out.

Note: Image conversion supports coded profiles as well as demo profiles. Coded profiles are those created with CoPrA SP (Serialized Profiles). In this way, you can evaluate the profile quality from either coded or demo profiles when converting images.
If a coded profile is to be embedded in the converted image file using the Embed target profile option, CoPrA will decode and embed the profile in the converted image with a smaller grid size. This ensures that other applications display the converted file correctly. Note, however, that you cannot use this profile for production purposes as the profile quality is reduced. For that reason, such profiles are marked as LOW QUALITY VERSION FOR DEMO ONLY in the file name.
